Impact of Large-Scale Wind Power Penetration on the Static Voltage Stability Based on the L Index

Abstract

This paper uses the L indexes to analyze the impact of large-scale wind power penetration on the static voltage stability of the power system. First it presents some common indexes in analyzing voltage stability. Then, it introduces the principle of the L index. After that, Simulation based on the L Index of a typical power system interconnected with large-scaled wind power shows the grid alternatives have a considerable impact on the voltage stability. Finally it gives the conclusions.
